SPECIFICATION forming part of Letters Patent No. 597,477, dated January18, 1898.

- Application filed July 293 1897. Serial No. 646,357. (No model.)

To aZZ whom it may concern.-

Be it known that I, MILETUS J. INE, of the city of Viashington, in theDistrict of G0 lumbia, have inventeda new and useful Measuring-Pump, ofwhich the following is a speci fication.

The invention has relation to improvements in measuringpumps for drawinga determined quantity of a fluid from a reservoir or containing vesseland delivering it directly into the portable receptacle; and the objectsare to simplify the construction and increase the efficiency of themechanism and insure accuracy in movement.

I accomplish the objects of the invention by the mechanism illustratedin the accompanying drawings, wherein- 'Figure l is a side elevation ofthe measuring-pump complete and vertical section of the pump cylinderand piston disposed in the fluid reservoir or tank. Fig. l is a detailof the delivering-nozzle, showing the valve secured therein. Fig. 2 is aplan view of the plate adapted to be secured to a floor above the tankand to which the pivot-ally-mounted stop is secured. Fig. 3 is a planview of one of the cross arms or heads of the measuringframe andcross-section of the hollow pistonrod. Fig. 4 is a view in elevation ofan auxiliary delivering tube or spout designed to be connected to thenozzle of the ump to fill deep or large cans.

This pump is particularly intended for use in measuring inflammable11iidssuch as coal-oil, gasolene, and similar fluids-end is designed tobe placed with the operating filling mechanism above a floorin onecompartment, with the pump extending below the floor and into a tanksecured and placed in a safe place.

Referring to the drawings, A designates a tank or reservoir of anysuitable size and of a construction adapted to contain with safety aninflammable fluid. In this tank is secured a pump-cylinder 1 of anyproper size and fastened in the bottom of the tank. This pumpcylinder ismade of a capacity suited to pump and measure the largest quantitydesigned to be delivered at the nozzle of the pump at a single stroke.In the drawings I have shown the pump-cylinder as seated on a perforatedstand or support 2, secured on the bottom of ends lodged on the flangeof the stand and their upper ends bearing against the top or cover ofthe tank. A guide-frame for the piston-rod is provided, being composedof side rods 4 4, let through ears on the pump-cylinder, said rods beingconnected at their upper ends by a cross-piece 5, formed with a centralhole through which the piston-rod slidingly operates and is guided.

In the bottom of the pump-cylinder is a suitable valve 6, opening upwardin a wellknown manner. This part or portion of the pump above describedI make no claim to, and it may be of other constructions suited to ameasuring-pump having a reciprocating hollow piston-rod.

In the pump-cylinder is disposed the reciprocating hollow piston-rod 13,consisting of a metal tube of the desired bore to freely deliver thefluid through the nozzle. At the lower end of the piston is carried thepistonhead 7, fitted to the pump-cylinder and provided with a valve 8,opening upward, so that when the piston is moved upward the requireddistance to measure the required quantity of fluid and is then moveddown to its limit of movement the quantity of fluid to be measured willbe delivered through the nozzle into a can placed to receive it. Theupper end portion of the piston-rod is curved over and directed straightdownward, as at 9, and in the nozzle is placed a valve 10 to stop thedrip, this valve being moved outward and away from the nozzle by theforce of the dis charging fluid and returned to close the noz zle whenthe flow is completed or the pressure ceases by means of a retractilespring 11. On the nozzle end portion of the piston-rod is fixed a hook12, on which is hung the bail of a light can while being filled,substantially as r causes the oontentstofroth andfoam rise outofthecanand. run down theoutcr surfacethereofonto thefloor, t-h us making adangerous deposit, besides making'it neces 'sary to clean both the canand the door, To "allay this'produced :ebullition and prevent theoverflow occasioned thereby limake'l the nozzle-piece let considerablylonger: than usual, extendingwell downin-to the'can be ingfilled, sothat thefluid will rise up and "around the lowergportion thereof andclose the same and the can maybe filled to; come I pletion; withoutanyappearanoeof the agitaused.

as the auxiliary nozzle piece is longenouglr to permit thereciprocationsofthe piston-rod. mThe upper portionof the tube is split,as

'- at 15 and is formed with a turn ord in flange I a, to take: over ahead or ring on the 1102 I 'zler, WVhen large'vessel l st-measured intoI and thedesired amount of fluid has beendis charged, the piston-rod maybe lifted and the auxiliary tube or nozzle be detached therefrom andthen withdrawn from the nozzle.

D designates a rectangular measuringframe secured to the piston-rod andso disposed thereon inrelation to the action of the piston that thelimits of its adjusted and determined movements will cause the piston todischarge the requisite and desired quantity of fluid into the can orvessel at a single downstroke of the piston-rod. This measuring-frame Dis of the following-described construction Referring to Fig. 1, l6 and17 designate upper and lower cross pieces or heads, preferablyconsisting of duplicate alining bars (see Fig. 3) formed withoppositely-directed semicircular central recesses 18 18 totake in andhold the piston-rod and at the ends formed with recesses 19 19 to clampand hold the respective ends of the measuring-bars. 20 and 20 designatethe measuring-bars of the frame, having their upper and lower endsadjustablysecured in the cross-heads 16 and 17 by means of upper andlower nuts 21 21 threaded on the respective ends of the bars anddisposed above and below the crossheads, substantially as shown in thedrawings. The alining bars of these cross-heads are held together,clamped to the piston-rod by clamping bolts or screws 22 22 It willvb'ecreadi'lyperceivedthat these cross-bars 16 andllmaybemade;insingle'integral pieces formedwith apertures totakethepiston-rod and ,m'easuringbarsand secured to the pis ton rod byanysuitable fastenings. V r The 'measu'ringbars of the frame D areformed or provided withsuitable steps 23 23 7 designed tolimit'rthelmovementof the p n mp and arranged therein or secured thereonat certain distances, determining: the-"required,

The stops or loops of the measuring-bars are disposed inalinement, with their inner ends adjacent to the piston-rod,substantially as shown in the drawings, and when the largest quantity isto be drawn they pass through the slots in the plate E, hereinafterdescribed.

On the floor is secured a strong metal plate E, having a piston-rodaperture 24 therein through which the piston-rod works, and, from thisaperture 2et, leads opposite the slots 25 25 through which the stops orloops may pass, or both of them, as when measuring a halfgallon. A

To stop the upward movement of the pump at the determined distances tomeasure a pint or quart, I pivotally secure on the plate E to move inthe plane thereof a latch or stoppiece 26, formed with bent or curvedarms 27 27 so formed and disposed that either may be moved ovelftheslots in their path and stop the loops'in the measuring-bars from comingfarther through the slots, and should it be desired to measure the fullcapacity of a stroke of the frame the stop-piece 26 is turned so thatthe ends of both arms thereof stand clear and away from the slots andthus permit both loops to move unimpeded therethrough. To hold therespective ends of the stop-piece 26 securely down over the slots, anoverhanging flange 28 is formed on the plate IIC E around thepump-aperture, the overhanging part of the flange serving as keepers forthe respective ends of the stop-piece when moved over the slots, asindicated in Fig. 2 of the drawings.

To adjust the frame to the measurements of the pint and quart, the uppercross-head of the frame is adjusted thereto by means of the adjusting-nuts on the upper ends of the measuring-bars, and the requisiteadjustment for the half-gallon or greatest measurementis made bymovement of the lower crosshead of the frame. After these adjustmentshave been made and ascertained the frame will need no furtheradjustment.

The operation and use of the pump are as follows: The pump having beenset up substantially as illustrated and the measurement adjustmentshaving been made as specified the vessel to be filled is hung on thehook on the nozzle. If a large vessel is to be filled, it is set on thefloor, with the long nozzle-piece therein. The piston is then raised tothe required and set distance and forced downward, when the determinedand desired quantity of fluid will be discharged.

hat I claim is- 1. In a measuring-pump, the combination with avertically-reciprocating piston-rod, of a measurin g-frame carried bythe said pistonrod, composed of upper and lower cross-bars secured tothe said piston-rod and measuring side bars, in the ends of thecross-bars, formed with loops disposed at determined distances in saidbars, and means to limit the upward movement of the frame andpiston-rod.

2. In a measuring-pump, the combination with a vertically-reciprocatingpiston-rod, of

a measuring-frame carried by the piston-rod, and composed of upper andlower cross-heads, secured to the piston-rod, and measuring side barsconnecting the cross-bars and having stops therein disposed atdetermined distances, means to adjust the cross-heads on the side bars,and means to stop the upward movement of the frame and piston-rod.

3. In a measuring-pump the combination with a vertically-reciprocatingpiston-rod, of a measu ring-frame carried by the said pistonrod andcomposed of upper and lower crossbars secured to the piston-rod, andmeasuring side bars connecting the cross bars, and formed with integralloops disposed at determined distances; means to adjust the crossheadson the side bars, and means to stop the upward movement of the frame andpistonrod.

4:. In a measuring-pump, the combination with a vertically-reciprocatingpiston-rod, of a measuring-frame, carried by the piston-rod, having sidebars formed with measuringstops, a suitably-supported plate formed witha piston-rod aperture and slots leading therefrom to'admit the passageof the measuringframe, and a pivotally-secured stop-piece formed witharms adapted to move over the said slots and stop the passage of thesaid frame.

5. In a measuring-pump, the combination with a vertically-reciprocatingpiston rod, of a measuring-frame secured to the piston-rod and havingside bars formed with stop-loops, a suitably-mounted plate formed with apiston-rod aperture and slots for the piston-rod and frame-bars to passthrough, and having a keeper-flange about the piston-aperture, and apivotally-mounted stop-piece on the said plate formed with arms arrangedto move across the said slots and under the said flanges.

In witness whereofI have hereto set my hand in the presence of twoattesting witnesses.
